Unfortunetly 1-carboxy has been discontinued. However I highly suggest looking into USP Labs Powerfull (the real thing as far as 1-carboxy) if you really want to give it a try. I am actually running two bottles at the moment and loving it. Plus the price is very resonable for any duration of use.

It's not something we're doing right now, but if there's enough interest like most products we can bring it to NP. I'm not positive if we will see bulk powerfull in the future, but that might be an alternative.
